SAFETY GAS-COCK.

Specification of Letters Patent.

Application filed February 20, 1906. Serial No. 301,987.

Patented April 2, 1907.

T0 at whom it may concern.-

Be it known that I, CHARLES L. GE FRORER, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Safety Gas-Cock, of whichthe following is a specification.

My invention consists of a gas-cock which when closed is adapted toremain in that condition, thus preventing any improper escape of gas atthe burner and whose plug is controlled against displacement.

Figure 1 represents a perspective view of a safety gas-cock embodying myinvention. Fig. 2 represents a partial top or plan view thereof and apartial horizontal section on line w m, Fig. 3. Fig. 3 represents alongitudinal section on line y y, Fig. 2. Fig. 4 represents alongitudinal section showing the cock in closed condition. Fig. 5represents a perspective view of the plug of the cock. Fig. 6 representsa perspective view of a detached portion.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates the body of a gas-cock, and B Bdesignate sections of opposite gas-pipes connected therewith, said pipesforming continuities of said body in the same longitudinal direction.The interior of said body A forms the seat for the plug C, which hasports or passages therein, usual in such case, whereby the gas may beturned on or cut off.

D designates a stirrup which occupies a position on the exterior of thebody A and has its ends connected with the lug C, it being noticed thatthe upper end of the plug has a groove or recess E therein, the samereceiving the adjacent terminal of the stirrup, the sides of said recessforming shoulders which embrace said terminal. A screw F is passedthrough said portion of the stirrup into the plug at the base of saidgroove and when tightened on the stirrup firmly connects the latter withthe adjacent end of the plug, said portion of the stirrup thus beingpositively connected with said plug and so prevented from shifting ordisconnection. The other terminal ortion of the stirrup is connectedwith the ower end of the plug by the screw F, which passes through saidportion of the stirrup into the end of the lug, it being noticed that awasher G is interposed between the portion of the stirrup and the adjacent surface of the body A.

As the stirrup is connected at both of its ends with the plug, thelatter may be readily rotated by the stirrup and so moved into closingor opening position.

For convenience of o eration of the stirrup it is provided with a handleH, which projects outwardly or laterally from the same, and so isconvenient of access.

The operation is as follows: The gas may be turned on to full extent bymoving the stirrup in the present case to the right, the position ofparts being shown in Figs. 1, 2, and 3, it being evident that thestirrup may be moved to partial extent to lower the light, if sorequired. hen the gas is to be turned off completely, the stirrup ismoved in the opposite directionin the present case to the left, when thelug assumes the position shown in Fig. 4, the effect of which isevident. It will be noticed that the end Walls of the body A act asstops for the stirrup, and the contacting of the stirru with the endWall at the left indicates that t e plug has been completely turned, andso the gas is fully cut ofi without the liability of escaping unburnedat the tip.

To prevent any strain on the stirrup as it strikes either stop, the headJ of the screw K, which connects the handle H with thestirrup is on theinner side of the latter and is adapted to abut against the end walls ofthe body, which walls in the present case are of the form of beads orshoulders L. (See Fig. 4.) Again, as the stirrup is connected with theends of the plug, the latter is controlled against displacement from thebody A either by rising therein or dropping therefrom, thus preventingany possible escape of gas from said body at the top or bottom thereof.Furthermore, the stirrup obviates the use of shoulders or stops on theplug and shoulders on the body around the opening which said plugoccupies. Again, the stirrup Dis adapted to be made of a piece of lightmetal, and the terminal of one limb is fitted on the shoulder on thelower end of the gas-plug C, leaving the terminal of the other limb freeto be pushed or sprung into the recess E, whose side walls formshoulders, as has been stated, the same preventing lateral displacementof the last-named limb. The screws F F are then respectively passedthrough the terminals of the stirrup into the ends of the plug, thusfirmly connecting the stirrup, it being noticed that I utilize theshoulder on the narrow end of the plug for the connection of one limb ofthe stirrup therewith and form the recess E in the wide end thereof forthe connection of the other limb of said stirrup, said limb being seatedin said recess flush with the end of the plug, thus producing a simple,compact, and inexpensive device for the purpose intended, the gas-plug Cas such not materially altered, excepting in the removal of thethumb-piece or handle heretofore integral with said plug and thesubstitution of the recess E therefor. Again, the screw K, whichconnects the handle H with the stirrup D, has its head J on the innerside of said stirrup, the same being somewhat ta pering and constitutinga practical stop for the opposite motions of the stirrup in opening andclosing the cock.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A gas-cock having a plug, an operative yoke therefor, one end of saidplug having a transversely-extending recess therein, one terminal ofsaid yoke being connected with the other end of said plug, and the otherterminal of said yoke being seated in said recess and embraced by theside Walls thereof, and a securing-screw, the latter passing I throughsaid terminal into said plug, and abutting said walls, said yoke freelyembracing the body of the cock, and being adapted to .abut in eitherdirection against said body.

2. A gas-cock having a plug, a yoke, the latter having its terminalsextending from the opposite ends of said plug, and screws for connectingsaid terminals with said ends,

said plug having one of its ends formed with a transversely-extendingrecess, and the adjacent terminal of the yoke being seated in saidrecess, and being embraced by the side walls of the latter, said yokefreely embracing the body of the cock.

3. In a gas-cock, a body, a plug and a yoke, the latter having itsterminals extending from the ends of said plug, means for connectingsaid terminals with said ends, and a handle on said yoke, one of saidheads having therein a transversely-extending recess, and the adjacentterminal being seated in said recess and being embraced by the sidewalls thereof.

4. A gascock consisting of a body, a plug and a yoke, the latter havingits terminals connected with the opposite ends of said plug, a handlefor said piece, and a screw connecting said handle with said yoke, thehead of said screw being on the interior of said yoke, and forming asingle stop to abut against the body of the cock in the opposite motionsof the yoke.
